  • Abstract
    The chemisorption of gases on the surfaces of semiconducting materials can result in measurable changes in the electrical conductivities. This effect has been widely investigated as a means of detecting both flammable and toxic gases. The authors discuss the properties of metal oxide sensors, e.g. SmO2, ZnO and Cr2O3 and consider their selectivity and temperature related behaviour
